The present invention relates to the cooling of gas Vfor the vremoval of its kcondensible vapors.

InY the manufacture f of combustible gas for industrial or domestic consumption, itis customary to employ a relief yholder atv the outlet of the generating apparatus. lThe holder may serve Aseveral-purposes, for example, to Y receive a fluctuating supply of gas from the generating apparatus and to kdeliver a supply more uniform in quantity andquality to the auxiliary apparatus such as puriers and also to'relieve thegenerating apparatus of the back pressure producedrby the auxiliary apparatus.'` y. i

- For instance, in the manufacture .of carburetted water gas, the gas is produced intermittently by the individual water 'gas sets,

and although when there is a plurality of sets in operation, the gas making periods overlap and tendrto produce amore steady out-put, the flow from the generating apparatus as a wholefluctuates. considerably.

The relief holder` receives this supply which fluctuates both in quantity andv quality and functions to deliver` a steady supply of gas of moreA uniform/quality through lthe eX- hausters to the purifying apparatus.

If the condenser is placed on the inlet of the relief holder, undue back pressure may be thrown on the generating apparatus. 'If

the condenser is -placed on the outlet of the relief holder, the generating apparatus is relieved of this back pressure, but the eX- hausters are subjected to undue suction, and gas is delivered hot tothe relief holder, containing large quantities of steam, occupying a large volume and requiring an undue reliefholder investment.

Thepresent 'invention isl directed `to the provision offa condenser and a relieffholder arrangementwhich doesnotthrow undue fback pressure on the generating` apparatus or create undue suction in the exhauster'inlet and does not require undue relief holder investment. At thefsame time it providesfor desirable counterilow relation between' the gas and the condenser cooling water, discharging all of the water but slightly below the temperaturer of the uncooled gas, and

'tion and in which,- y F ig. l shows the apparatus of the inven- 'tion in partial elevation and partial vertical passing the coolest water in heat transfer relation only with. the cooled gas about to be discharged, to the eXhausters. rThe invention willl be more particularly described in connection with the attached part of this specificadrawings which form a plan viewof the apparatus er" illustrated is divided intofa numberV of passes by the partitions 4, and istraversed. by the tubes 5 which terminate in the Vupper and lower tube sheets 6 and 7 respectively.

`The partitionsy 8` and 9 in` the upper andv ylower water spaces serve to provide passes A"for thewater from the water inlet 10 to the f water? outlet Il, in counterlow relation to ,the passage of the gas. f Intermed'ate of the gas inlet and'outletis yprovided* the connection 12,1 furnished with they valve 13 leading from the condenser to the relief holder.

' In operation, rfor instance, when vemployed with carburetted water gas apparatus, the hot gas passes from the Water gas set'or sets to the 1 gas inlet 2v and traverses the passes of the Vso If thesupply of gas tofkthe inlet 2 is greater ythan that being drawn by the eXhausters (not shown) from the outlet 3 plus the decrease in volume dueto cooling, the excess'V gas passes through the connection l2 to the holder let. The remainder of the gas passes through the following passes ofthe condenser n to the outlet '3.

When the supply of gas to the inlet is in! Y apparatus, andthe. gas outlet 17 leading to A'ftion to the gas and thence byconnection 21l to the condenser 15, and through it incounter'- suflicient to supply the steady demandof the exhausters, the gas which has passed to f the holder is returned through theconnection 12 and is passed through the passes ofthe condenser between the connection 12 and the gas outlet` 3,'bein'g Vreduced thereby toV the proper temperature.

Condensing water passes from the Water finlet 10 through the tubes in the successive passes to the waterv outlet 11, cooling first the gas vabout to leave the condenser through the outlet 3 and linallythe hot gas frointhe generating set.

The gas llow throughthe passes between- Vthe gas inlet 2 and the connection 12 iiuctuatesy with variation in gas generation, while theflow through the Vpassesbetween the connection 12-and the .gas outlet f3 is steadyas governed by the exhausters. The gas in pass-v ving .through the'tirst passes is cooledand reducedin volume, reducingtherelief holder investment.V The water'used in cooling the V gas .passing througlrthe latter passes, in-

cluding the gas returned from the holder, Yis

further utilized for cooling` the hotter gas iiowing through the firstV passes.

Referring to Fig. 3, Y This iigure shows a niodiiication of the apparatus of Figs. l and 2 in that the connection to the relief holder leads from a connec- Ytion between two of -a battery of condensers "instead of intermediateof the gas inlet and outlet of one condenser. A Y

coolingvkwater Venters condenser 18 through inlet 20,`flows through it in counteriow relal flow relation tothe gas tothefwater/outlet 22 Y as shown by the dotted arrows. v2 2 is the relief holder. The connection 24, provided with thevalve 25, leads from connection 17 to the relief holder. Y Y Y The operation is as in v1 2. The

4condenser 15, Fig. 3, performsV the same function` as the first passes of condenser 1 in V.,Fig. 1 and the condenser 18, Fig. 3,-the same 'functions as the latter passes of condenser f1 in Fig. 1, and th'econnection 24' the same function as 13 in Fig..1.

'The water used in cooling theVV gas flowing through condenser '18 including the gas revturnedfrom therelief holder is further utilized in cooling the hotter gas flowing through condenser 15. Y

Referring to Fig. 4,- Y

In thismodication of the apparatus there 'are two connections leading to the relief .holder from a connection between two condensers of aV battery of condensers.

26 'indicates one condenser of the battery provided with the hot gas inlet 27 and further provided with the gas outlet 28 furnished with valve 29 and leading to the con'- denser 30 which is further provided with'the gas outlet 31 leading to the eXhauster.' The connection 39, provided with valve 32, leads; from the connection 28 (intermediate of the condenser' 26 and the valve 29) to the relief holder. g the valve 34, leads from .connection28 (intermediate of the condenser 30 .andthe valve 29) tothe relief holder. The cooling water mea-ns arey arranged as in Fig. .3. yThe cool water enters the battery at the Vwater inlet 35 of condenser 30,.f1ows V80 Athrough that condenser in counterilow 'rela-l tion to the gas and'thence through connec`- TheV connection 33, provided with n n tion V36 to condenser 26 and through that condenser in counterflow relationto the gas to Ythewateroutleti.

In operation, if valve x F135 29, and .one or both.V .f

of valves32 and 34 open, the,apparatusfunc-1` n tions as in Fig.v In periods of greater prolductiointhc excess of gas over the demand by the exhauster goes to therelief holder after i passing through' condenser 26there1nainder passing through condenser V30 tothe exhauster. Duringperiods of lesser production, .gas is returned from the relief'holderandpassed through condenser 30,7together with thegas' passing from Vcondenser 26. If the valvey 291 is closed, with valves32 and 34 open, all of the gas passing V.through condenserY 26 .passes through connection Slto the relief holder and lcondenserf() to the exhauster.

` The cooling )vater used in cooling thegas passing thro-ugh condenser 30 is utilized in cooling thehotter gas lpassing through V,con-
